MacRumors is reporting this morning that Intel is moving forward with launching their Arrandale mobile CPUs in early January. These particular Arrandale CPUs are based on the "advanced Nehalem architecture" first introduced into Macs just this year.

Intel plans to launch four 32nm dual-core Arrandale CPUs (Calpella platform), the Core i5-520M, Core i5-430M, Core i3-350M and Core i3-330M, in the first half of January 2010 for the mainstream notebook segment, according to sources from notebook players.

The ramifications of this development could be significant, given the hype surrounding the next line up of product offerings from Apple.

According to published reports, the four new mobile processors will come in both mainstream and low-voltage varieties, which means they will work with the MacBook Pro and the MacBook Air. Either way, the new chips will immediately increase the overall performance of Apple notebooks currently available.

The new CPUs, together with the recently released Windows 7, are expected to help boost demand for notebooks in the first quarter of 2010, the sources predict.

The processor exciting most Apple fans is the Intel Arrandale Core i5-430M. While its top clock speed is comparable to that of the Core i3-350, the 430 boasts Intel's Turbo Boost technology, which enables each individual core to hit speeds up to 2.53 GHz.

Intel will launch six more CPUs in the third quarter of 2010 with some models under its Pentium brand for the same segment, the sources noted.

The last MacBook update from Apple came in what seems to have been ages ago - June of this year.
